Answer:
3/5
Explanation:
You want the rate of change between points (1/3, -2) and (2, -1).
Slope
The rate of change between two points is the slope of the line that contains those points. It is found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (-1 -(-2))/(2 -1/3) = 1/(5/3) = 3/5
The rate of change is 3/5 = 0.6.

Additional comment
The attachment shows the equation of the line in slope-intercept form is ...
y = 0.6x -2.2
The slope (rate of change) is the coefficient of x, which is 0.6 = 3/5.
